From reading many posts abut this subject, it has lead me to believe that the new imac refresh has actually downgraded the graphics capabilities and here in the UK has increased in price. HD2600 = dedicated 9400m = integrated will adding more ram increase the amount of Vram? (1gb = 128mb vram) i can get a refurbed 20" w/256mb vram for £810 whereas the new imac with supposedly worse specs costs £945 Does anyone know what the actual upgrade was if any? not downgrades!!
